“The father left for the evening and returned home. He is the one that made that phone call to us,” said Denver Police Cmdr. Ron Saunier.

Police won’t confirm the motive or if a suicide note was left.

Tony Nunez said he has no idea what drove his sister to do such a terrible thing.

“Whatever drove her to this it’s going to be in God’s hands. He will be the judge of her and from now on we need to focus prayer on our little niece,” said Nunez.
